Cycles: Turning | ADAPT ROTARY COORDINATE SYSTEM
(Cycle 800, DIN/ISO: G800)

Effect

With Cycle 800 ADAPT ROTARY COORDINATE SYSTEM, the
TNC aligns the workpiece coordinate system and orients the tool
correspondingly. Cycle 800 is effective until it is reset by Cycle 801,
or until Cycle 800 is defined again. Some cycle functions of Cycle
800 are additionally reset by other factors:
Mirroring of the tool data (Q498 REVERSE TOOL) is reset by a
Tool Call.
The function ECCENTRIC TURNING Q535 is reset at the end of
the program or if the program is canceled (internal stop).

Please note while programming:

The Cycle 800 ADAPT ROTARY COORDINATE SYSTEM
is machine-dependent. Refer to your machine manual.
Software option 50 must be enabled.
Software option 135 must be enabled.
The machine tool builder determines the configuration
of your machine. In this configuration if the tool spindle
is defined as the axis in the kinematics, the feed-rate
potentiometer is effective with movements with Cycle
800.
The tool must be clamped and measured in the correct
position.
You can mirror the tool data (Q498 REVERSE TOOL) only
if a turning tool is selected.
Check the orientation of the tool before machining.
To reset Cycle 800, program Cycle 801 Koordinaten-
System zurücksetzen.
Cycle 800 limits the maximum permitted spindle
speed during eccentric turning. This results from a
machine-dependent configuration (implemented by your
machine tool builder) and the size of the eccentricity.
It is possible that you programmed a speed limit with
FUNCTION TURNDATA SMAX before programming Cycle
800. If the value of this speed limit is less than the
speed limit calculated by Cycle 800, the lower value
is effective. To reset Cycle 800, program Cycle 801.
This also resets the speed limit set by the cycle. The
speed limit is then effective that you programmed with
FUNCTION TURNDATA SMAX before calling the cycle.
If you use the settings 1: MOVE, 2: TURN, and 3: STAY
in parameter Q530 Inclined machining, the TNC
activates the function M144 (also see the "Inclined
Turning" User's Manual).
